Cell immaturity and white/beige adipocyte potential of primary human adipose-derived stromal cells are restrained by culture-medium TGFβ1

Abstract: Human adipose-derived stem/stromal cells (hASCs) can differentiate into specialized cell types and thereby contribute to tissue regeneration. As such, hASCs have drawn increasing attention in cell therapy and regenerative medicine, not to mention the ease to isolate them from donors. Culture conditions are critical for expanding hASCs while maintaining optimal therapeutic capabilities. Here, we identified a role for transforming growth factor β1 (TGFβ1) in culture medium in influencing the fate of hASCs during… Show more

“…So far, the molecular mechanisms underlying the stemness of ASCs remain poorly understood. However, the known antiadipogenic factor, transforming growth factor (TGF)β [44,45], is able to regulate the identity and function of DPP4+ cells [24]. In fact, treatment with TGFβ increased the proliferative capacity of ASCs, inhibited adipocyte formation (even when using a CAC), and upregulated the expression of ASC-specific markers,…”

“…The expression of GYG2 increased rapidly during beige adipogenesis (Figure 5f ). Additionally, the expression of GYG2 was analyzed using RNA‐Seq data from forskolin‐treated adipocytes in GSE134570 (Min et al., 2019 ), which mimics the transdifferentiation of beige adipocytes from white adipocytes in vitro (Lemenager et al., 2020 ; Whitehead et al., 2021 ). GYG2 expression was significantly higher in forskolin‐treated adipocytes than in vehicle‐treated cells (Figure 5g ).…”

“…Self‐organized vascular formation in close proximity to adipocytes was achieved via the refinement of our previously published medium. [ 18 ] Inhibition of the TGFβ pathway has been shown to favor the differentiation of adipose progenitors toward adipogenesis, [ 69 ] including toward the beige lineage. [ 70 ] Furthermore, such inhibition decreases ASC differentiation into myofibroblasts.…”
